I have an R9 280x discrete GPU and I'm just having fun with my Intel HD 4600 iGPU.
It can run some games like Assassin's Creed Rogue and Metro Last Light very fine on low graphics at 720p.
It can even run Call of Duty2(1200p) and World at War(1050p) on high settings with anti-aliasing off of course.
Do you guys know the voltage limit allowed for it before iGPU/CPU degradation?
Right now it's just at 1.360v while running at 1650mhz on the GPU core.
RAM frequency is at 2400mhz single channel.
